Latest Patents

Lang's latest patents focus on systems, methods, and devices for dual closed loop modulation controllers for nonlinear RF amplifiers. These inventions are designed to facilitate RF envelope amplitude control. For instance, one of his RF envelope amplitude control systems includes an RF amplifier associated with a feedback device that generates a first feedback signal representing the power in an RF output signal. Additionally, it features a transmit waveform generator that produces a reference waveform signal. An adaptive table waveform generator compares the reference waveform signal with the first feedback signal to create a second feedback signal based on that comparison. Finally, a loop filter combines these signals to form an amplifier control signal, which is then provided to the RF amplifier to adjust the RF output signal to conform to a specified RF envelope.
